In recent years, there has been growing interest in storing energy produced from rooftop photovoltaic panels in a home battery system to minimize reliance on the electric utility. A number of vendors have sought to capture this emerging market, including electric vehicle market leader Tesla and German home energy storage provider Sonnenbatterie. Notably, Tesla has partnered with Green Mountain Power, one of the largest electric providers in the state of Vermont, to offer home storage to its customers; and Sonnenbatterie has partnered with Sungevity, the largest private solar company in the United States.
